Hi Mary:
It is certainly a Nerine sarniensis hybrid, but whether it is a named
variety would be hard to determine. Many of the named varieties and unnamed
crosses can be very similar in color and appearance. I think it will self
pollinate. If you want pollen write me privately and I can send you some
from a number of clones we currently have in flower.
All the best,
